After the discovery of the ozone hole over Antarctica, assessment of the long‐term trend of ozone in different regions of the globe has become a frontline topic of Earth system sciences. Trends in total ozone column (TOC) have been estimated by various authors [ McPeters et al ., 1996; Hollandsworth et al ., 1995] using the data obtained from the Dobson spectrophotometer, satellite‐borne instruments, and balloon‐borne ozonesondes. Most such studies are for mid‐ and highlatitude regions, whereas studies made with data from low‐latitude regions are meager. No detailed sensor‐based approach has been undertaken so far to understand the total ozone scenario from an Indian perspective, apart from a few observations [ Chakrabarty et al ., 1998] that were largely based on a ground‐based Dobson spectrophotometer at major Indian cities.
